' i VAPOR CONDENSER FOR'RADIATORS.

Application filed vAugust 8, 1925. Serial No. 49,025.

This invention relates to condensing devices and pertains particularlyto a condenser device adapted to be attached to the filling inlet of anVautomobile radiator.

The primary object of this invention is the provision, in a manner ashereinafter set forth,fof a vapor condenser which when attached to theradiator of an automobile, will receive and condense the vaporsgenerated in the radiator and return the liquid to the rae diatorthereby preventing the loss of the same through evaporation. A device ofthis type is particularly desirable during the season when alcohol orother easily volatile liquids'are placed in the radiators with the waterto prevent the freezing of the same. A slight rise in temperature of theliquid causes the alcoholto be vaporized and unless some device of thischaracter is employed the alcohol will be quickly dissipated. The deviceis also very efficient for summer use for it obviates the necessity ofhaving to continually refillthe radiator when the liquidv therein israised tov a high degree of Vtem- F perature through long continuousdriving of the machine.

A further object ofthe invention is the provision, in a manner ashereinafter set forth, of a radiator attachment of the type describedwhich will be of neat and attractive appearance making a very desirableornament for the vehicle.

A still'further object of the invention is the provision, in a manner ashereinafter set forth, of a condenser which will be of simpleconstruction, strong and durable7 and elfi` cient for the purpose setforth.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection Vwith theaccompanying drawing forming a part of this specification, with theunderstanding that the invention is not confined to any strictconformity with the showing'of the drawing but maybe changed andmodified so long as such changes and modifications mark no materialdeparture from the salient features of the invention as expressed in theappended claims.

In the drawing:

Figure 1 is a longitudinal sectional view taken through the deviceembodying this invention, taken upon the line 1 1 of Figure 2.

u Figure is av section taken upon the line 21e-'2 of Figure 1i j Figure3 isa section taken t upon the line 3 3 of Flgure 1 and, l

Figure 4 is a section taken upon the liney the head 3 the interior ofwhich Vhead is i threaded as indicated at 4. Formed within the bodyacross the interior of the same at a point adjacent the lower portion ofthe head 1 is a wall or partition 5 which divides the body into an upperand lower chambered portion 6 and 7 respectively.

Tithin the lower portion 6, there is set up a .smaller chamber or well 8by the formation of the wall 9 within theportion, the upper part ofwhich wallmerges with the partition 5 and the lower portion with thebottom 10 while the side edges thereof merge with the wall ofr theybody 1. Formed through the partition 5 is an inlet aperture 11whichopens into the well 8 and threaded' i into the bottom 10, is a plug12 which closes a drain opening inthe lower portion of the.`

well. This plug'12 has a recess 13 formed in the end thereof whichcommunicates with a downwardly extending passage 13;L formed through thelbottom 1 and into this .down-y wardly extending passage the end of athumb screw 14 is extended to normally close the same. When the well 8is to be emptied the thumb screw 14 is removed and the contents of thewell allowed to flow` therefrom through the passage 13 into the lowerportion 6.

. Threaded into the lower end of the body 1 is a closure 15 which isprovided with a centrally threaded aperture in which a nipple 16 isdesigned to be engaged.

When the device is to be secured to a radiator, the radiator cap, asmall portion of which is indicated at 17, has a passage bored throughthe central portion thereof through which passage the nipple 16 isextended. A washer 18'is then positioned over the inner i end of thenipple and a securing nut 19 the* body securely against the outer sideof the'cap. The device is thus secured in posi tion upon the radiatr capand the may shown.

be inserted or removed into or from the radiator as desired. i

Coiled or wrapped about the outside of the body portion 1- beneaththehead 3, isa condenser pipe or tube 2O formed preferably of coppertubing, and the lower end of this tubing is extended through the sidewall of the body as indicated at 2l while the uppery end enters the bodyat a point slightly beneath the partition 5 and extends upwardly andinwardly thereinto and through the partition las indicated at 22,opening into the upper portion 7 in the head 3.

Extending through the partition 5V is ann other tube, which tube isstraight and relatively short as indicated at QB. The lower portion ofthe tube 23 extends a slight dis-- tance beneath the partition 5 intothe portio-nI 6 while the upper portion thereof extends a substantialdistance above the partition 5 and above the top of the .head 3l Uponthe upper portion of theibody l there is mounted ay condensing globe 2awhich globe is preferably constructed of heavy glass. This globe asshown is hollow and has an opening formed therethrough from about theedge ofy which opening the exteriorly threaded collar 25 extends andthis collar is threadedintof the head 3 as is The upper end 22 ofthecoilQO, the extended upper portion ofthe tube 23 and the passage 1l allopen into this globe 24 as shown.

Formed at diametrically oppositeV points upon the head 3 ofl the bodyare two outwardly extending arms 26' andl 9.7' respectively, theterminal' outer ends of which arms are upturned as indicated at 28 andprovided with interiorly threaded axial re- Cesses 29, the lowerportions of which recesses have opening thereinto the ends of tubes 30which are embedded in and extend throughout the length of theirrespective arms. f The inner ends of these tubes extend through thepartition 5 in the body and are bent as at 31A-to curve downwardly intothe well 8. n

Threaded into the recesses Q9 in theends ofthe arms Z6-and 27 arecaps-32, hollow and having therein al plurality ofv transverselyextending apertured partitions 33. The tops of these caps areprovidedwith a series of openings 34 as shown. These caps together withthe associated structure-.con-

. stitutev` a relief structure for the condenser has-reachedthe pointvof. vaporization, thev vapors will pass upwardly into the globed,

through the tube 23 and also through the coiled tube Q0. The vaporspassing through.

05'? thetube 2O willbe-mostly condensed before reaching the globe 2eandv the condensed liquid willthen of course flow back through theoutlet 21 of the tube and back into the radiatori The vapors, passingthrough the tube Q3 will enter the globe 24 and be condensed therein,`the condensed liquid settling into the chamber T and flowing throughthe passage l1 intothe well 8 and through the upper end of the tube 22back through the coil: into the radiator. The well 8 will of Cou rsebecome filled eventually and the liquid in this well will seal theendsofv theztubes 30 against the escape of any vapor from the condenserdevice. In the event that the vapor is not condensed rapidly enough togrevent a stro-ng pressure being exerteduponthe interiory oftheglobe/24, the pressure set up will be elieved by forcingsoine of theliquidv from the well 8 through the tubes 30 into the cap 32 thusallowing the proper expansion of the vapor or the escape. of some ifnecessary.

From the foregoing description it willbe readily seen that there hasbeen provided va vapor condenser of unique design, simple inconstruction, inexpensive to manufacture and easily and quickly appliedas wells as one which will be efficientiv for the purpose set forth.
